Sand casting is one of the oldest and most widely-used methods of metal casting, dating back to around, and even before, 10,000 BC. The process employs sand for the main mold material, as this material can be shaped and compacted to form a variety of complex and large cavities for molten metal that will eventually be turned into metal castings for a host

· How Solar Cells are Made. Ultimately, every solar cell begins its life as quartz sand. Also known as silica sand, quartz sand consists of at least 95% pure silicon dioxide, which is also known as silica or as SiO 2. But we don’t need silica for solar cells, but silicon, which means we need to get rid of the oxygen, to leave behind pure silicon.
